[0002] With the rise of smart electronic products and the increase in functions, chargers have become a frequently used necessity in daily life. Since the data cable and the charger are separated, the data cable is easy to lose, so the charger is designed to store the data cable in a reel-style.

In order to achieve specific positioning, the general positioning mechanism of the reel-style telescopic cable is designed as a ball-type positioning. When releasing the wire, the wire is pulled out to a certain length and the wire is released to position. When reeling, pull the wire out to the preset length value and then release it, and the wire will be retracted at once. However, the pulling length that triggers the retraction of the wire is difficult to control, and a better customer experience cannot be achieved. Utility Model Content
